Rack up with the DMM Wallnut Set on your next trad climbing trip, and they'll amaze you with their easy selection and solid placement. Their color-coded anodized heads help you pick the right size the first time, so you can quickly slot the nut in a bomber constriction and move on before the pump clock starts ticking. Wallnuts also have a curved taper with a vertical concave slot to help them seat solidly in strangely shaped cracks.
